Make An X-Ray Exposure

  • First Trigger
    • Anode rotates
    • Filament voltage applied
      • Electrons boiled off filament but remain close
      • Edison effect (thermionic emission)
  • Second Trigger
    • High voltage applied between anode & filament
      • electrons accelerated into anode
      • release kinetic energy as x-ray photons
